这个问题在这里已有答案：
我有一个网站，只能在Chrome浏览器上访问。我想获取设备（主要是android标签）的唯一ID。这个值必须与imei相似。我想使用javascript获取此值。有没有办法使用JavaScript获取设备的唯一ID。
您可以为此目的访问设备的uuid
在Phonegap中，您可以使用Cordova Device Plugin
/* Android: Returns a random 64-bit integer (as a string, again!)
The integer is generated on the device's first boot
BlackBerry: Returns the PIN number of the device
This is a nine-digit unique integer (as a string, though!)
iPhone: (Paraphrased from the UIDevice Class documentation)
Returns a string of hash values created from multiple hardware identifies.
It is guaranteed to be unique for every device and can't be tied
to the user account.
Windows Phone 7 : Returns a hash of device+current user,
if the user is not defined, a guid is generated and will persist until the app is uninstalled
Tizen: returns the device IMEI (International Mobile Equipment Identity or IMEI is a number
unique to every GSM and UMTS mobile phone. */
var deviceID = device.uuid;
在MoSync中，您可以使用Javascript API
<!DOCTYPE html>
<html>
<head>
<title>Device Properties Example</title>
<script type="text/javascript" charset="utf-8" src="js/wormhole.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for Wormhole to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// Wormhole is ready
//
function onDeviceReady() {
var element = document.getElementById('deviceProperties');
element.innerHTML = 'Device Name: ' + device.name + '<br />' +
'Device Platform: ' + device.platform + '<br />' +
'Device UUID: ' + device.uuid + '<br />' +
'Device Version: ' + device.version + '<br />';
}
</script>
</head>
<body>
<p id="deviceProperties">Loading device properties...</p>
</body>
</html>
